2 Applications
The BGF meter is suitable for flow measurement of liquid or
gaseous products in pipes. The special advantage is that
it can be used for all directions of flow. It shows the
current flow rate in volume or mass per unit in time.
Applications: flow measurement, dosing, monitoring,
adjusting and control of liquid and gaseous products.
The meter’s design makes it ideal for processes under
difficult and adverse operating conditions.
The devices are available with additional electrical
equipment for process monitoring and control.
3 Operational mode and system
design
3.1 Measuring principle
The measuring element consists of a sharp-edged
measuring ring and a conical measuring body with a
compression spring.
If a medium flows with sufficient velocity through the
measuring ring, the position of the measuring body will shift
until the flow force and the measuring body plus the spring
tension establish equilibrium.
The position of the measuring body in the measuring ring
serves as the measure of the flow and is converted to a
rotary motion by the permanent magnet embedded in the
measuring body through a magnetic tracking system. It is
then transmitted to the scale and the additional electrical
equipment.
3.2 System design
The meter consists of a cylindrical fitting pipe with flange
connections on both sides, a measuring ring firmly inserted
in it and a vertically movable, conical measuring body.
The position of the measuring body resulting from the flow
rate is converted to a rotary motion on the pointer axis of the
analog indicator unit by the built-in permanent magnet
through the magnetic tracking system.

Heinrichs Messtechnik BGF Installation and Operating Instructions
5.4 Analog output with the KINAX 3W2 angle-of-
rotation transmitter
The signal output of the angle-of-rotation transmitter is
factory-calibrated to the scale values. The signal output is 4-
20 mA in 2-wire connection; or alternatively 0-20 mA in 4- or
3-wire connection. The signal output of 4 mA corresponds to
the flow rate scale value of 0 (0 mA for the 0-20 mA version).
5.6 mA corresponds to 10% of the flow rate scale value
(2 mA). 20 mA corresponds to 100% of the flow rate scale
value.
Use in hazardous areas:
The angle-of-rotation transmitter is a component approved
for hazardous areas. When used in hazardous areas, all the
values and instructions indicated in the certificate of approval
must be observed. Auxiliary power is fed through an
approved intrinsically safe circuit of 12-30 V. To prove
intrinsic safety, only authorized electrical equipment may be
interconnected. Please take note of the maximum
permissible ambient temperature of 60°C/75°C for the
transmitter and the process temperature.

3. With ES transmitter:
+/- 0.5 % / 10 K reference temperature 22°C
6.3 Influence of fluid temperature
Deviations in fluid temperature from the temperature
observed during calibration can result in a proportional
display fault because of the corresponding change in
density. Changes in viscosity cause a non-linear display
fault..
7 Conditions of use
The VDI/VDE guidelines 3513, Sheet 3, must be observed.
The meter is suitable for:
1) Liquids with sufficient flow ability that are free of
solids, do not bond and do not tend to settle.
2) Gases with linear flow behavior and an adequate
inlet pressure.
Viscosity factors will not be considered by the system.
7.1 Installation conditions
Vertical or horizontal installation, according to the direction of
flow specified in the order.
When mounting the device in the horizontal position, make
sure the indicator unit is not pointing upwards. This is to
prevent water lodging on the glass window and entering the
device under the protective shroud of the housing.
The limit values for temperature and air humidity at the
mounting location must be maintained. Avoid corrosive
atmospheres. If this cannot be avoided, ventilation must be
installed.
Please make sure that there is adequate clearance from
parts that might cause magnetic interferences such as
solenoid valves and ferromagnetic components like steel
brackets/supports. We recommend that the minimum lateral
distance between two adjacently mounted devices be
300 mm. The devices can be mounted close together if
vertically offset by one device length. The minimum lateral
clearance for interfering steel parts should be 200 mm. In
case of doubt, check the interference by moving the device
back and forth in the selected distance by about 200 mm
and testing whether the pointer position changes.
Select the mounting location so as to enable a reliable
reading of the scale values. Please take note as well of the
space requirement for any possible disassembly of the
device. As a rule, inlet and outlet sections in front of and
Page 6 of 29

Heinrichs Messtechnik BGF Installation and Operating Instructions
behind the device are unnecessary if the medium has a
linear flow profile. Avoid mounting accessories converging
on one side in front of the device. However, if this is
indispensable maintain a minimum device length of 250 mm
as an inlet section.
The nominal size of the pipes to be connected must
correspond to that of the meter. Avoid fittings converging on
one side directly in front of the device. As a rule, install
valves behind the measuring equipment if there are gases
involved.
7.1.1 Mounting/start-up
Before installation check whether the measuring element is
free from foreign bodies. The instrument must be mounted
vertically or horizontally according the planned and
confirmed direction of flow.
The nominal size of the device and that of the pipes must be
the same. The pressure stages and, hence, the dimensions
of the flanges must coincide. The surface roughness of the
flange sealing surface must be suitable for the prescribed
gaskets.
Please check whether possible accessories like spring
stops, gas/viscous-type damping sets are still correctly sitting
on the flange. Check whether the mounting clearance
between the flanges of the pipes corresponds to the
assembly dimension of the device plus two gaskets. To
achieve stress-free mounting, the flanges of the pipes must
be aligned parallel to each other.
Use connecting bolts and gaskets in the prescribed
dimensions. The gaskets must be suitable for the operating
pressure, the temperature and the measured medium. With
PTFE-coated devices, use gaskets whose interior and
exterior diameter correspond to the sealing strip of the
device.
Tighten the screws crosswise so that the process
connections are tight. See to the tightening torques of
screws especially with PTFE-coated devices.
The maximum torques for PTFE-coated devices are:
DN15/DN25 = 14 Nm/DN50 = 25 Nm/DN80 = 35 Nm/DN100
= 42 Nm (following VDI/VDE Guideline 3513).
Please check whether the pipe is adequately stable so that
vibration or swinging of the device is out of the question. (Do
not use steel mounting parts on the device.)
When gas is used as the medium, pay special attention to
the position of the valve. If the device is calibrated to more
than 1.013 bars absolute pressure, the valve is usually
installed behind the flowmeter. At 1.013 bars absolute
pressure (free exhaust) install it in front of the device.
If there is risk of dirt or solid matter penetrating the process
pipes, flush them beforehand so that these materials do not
get caught in the device. Ferromagnetic solid matter such
as spatter can lead to the breakdown of the device. If these
materials are still present during normal operating
conditions, mount a magnetic filter (accessory) in front of the
device. When using liquids, flush to avoid a surge of gas
bubbles. Slowly increase the supply pressure when using
gases to prevent pressure surges. Basically, avoid
activation using solenoid valves to prevent the measuring
body from shooting upwards.
7.1.1.1 Gas measurement
When using gases, slowly let the operating pressure rise. At
the same time, vary the operating pressure through a setting
valve so that the measuring body is not knocked around
since otherwise this would damage the measuring element.
7.1.2 Device settings
The measuring equipment is delivered ready for operation
according to your order specifications. The limit
transducers are set to the desired values. If you have
submitted no requirements, the basic setting for
1 contact device: - Minimum contact switching point at 10%
of descending flow (damped/closed-circuit principle).
2 contact devices: Minimum contact switching point at 10%
of descending flow and maximum contact switching point at
90% of ascending flow.
7.1.3 Adjusting the limit transducer
The contacts are adjustable through the contact position
indicators located on the scale. Dismantle the indicator
cover, unfasten the contact position indicators, set to the
desired value and reattach them.

Heinrichs Messtechnik BGF Installation and Operating Instructions
7.1.4 Operation in hazardous areas
7.1.4.1 Without electrical equipment
The basic version of the flowmeter is a non-electrical device
without its own ignition sources and meets DIN EN 13463-1
requirements. It can be used in hazardous areas that
require Category 2 equipment.
Marking: II 2GD c
Tech. File Ref. 03-02 X
Since the device does not have its own power sources that
would result in a temperature increase, the fluid temperature
is decisive for the maximum surface temperature.
When used in potentially explosive dust atmospheres, the
device must be cleaned regularly in order to avoid deposits
exceeding 5 mm.
7.1.4.2 With built-in electrical limit transducers
When the limit transducers are installed, the device becomes
an electrical assembly and receives a marking in accordance
with DIN EN 50014 from the entire device with the built-in
electrical limit transducers.
The electrical and thermal data and the special conditions of
the EC Type Examination Certificate of the built-in limit
transducers must be observed (see also the diagram in
Section 7.3.2).
The influence of the fluid temperature on the built-in limit
transducers must be observed. The overtemperature of the
maximum fluid temperature based on the maximum ambient
temperature must be considered with a factor according to
the following table:
Nominal size Factor for
standard
version

7.3.4 Inlet and outlet sections
Inlet and outlet sections are not required for a linear flow
profile of the fluid. For an extremely non-linear flow profile
(e.g. shut-off/control valves are located in front of the meter),
we recommend an inlet section with a mounting length of
250 mm (see also guidelines in accordance with
VDI/VDE 3513).

7.3.7 Pressure (for gas measurement)
The measured values only apply to the calibrated fluid data
stated on the scale. Any change or deviation in pressure
causes a display fault in gases. Viscosity factors cannot be
considered by the system.
Pressure loss: Depends on the device size and the
measuring range (see Measuring range table).

8.5 Magnetic filter
The BGF flowmeter is sensitive to impure media. Before
installing the device, clean the pipes of dirt, spatter and other
foreign matter. If the medium comes with solid particles,
connect a suitable filter in series. When dealing with flow
media with ferrous particles, we recommend the connection
of a magnetic filter.
To protect both magnetic filter types, MF-S (stainless steel)
and MF-P/S (PTFE/stainless steel), from corrosion,
encapsulated permanent magnets are laid out in spiral form.
The spiral mounting produces optimum effect at small
pressure loss. The filter can be supplied with groove or
tongue, projection or return, other standards or special
connections according to customer wishes.

15 Safety instructions
15.1 Intended use
The BGF variable-area flowmeter may be used only for flow
measurements of fluid and gaseous media. The
manufacturer shall not be liable for damages that may result
from unintended or inappropriate use.
When dealing with an aggressive medium, clarify the
material durability of all wetted parts.
When using the device in hazardous areas, follow the
applicable national installation rules.
15.2 Installation, start-up and operating personnel
Only trained specialists authorized by the system operator
may carry out the installation, electrical installations, start-up,
maintenance and operation. They must read and
understand the operating manual and follow its instructions.
The required mounting, electrical installation, start-up and
maintenance work may only be carried out by expert and
authorized persons designated by the plant operator.
Basically, follow the conditions and provisions applicable in
your country.
16 Packaging, mounting and
shipment
Carefully unpack the device to avoid damaging it.
The operability of the measuring cell can be tested by
pressing the measuring body upwards in the direction of flow
using, for example, a wooden stick. The pointer position of
the indicator mechanism must follow the direction of
movement. The resetting spring resets the pointer back to
zero after the magnet carriers are released.
With the help of the delivery note enclosed in the packaging,
check whether all technically relevant data coincide with your
requirements.
Storage and installation must be done in a clean and dry
room so that contamination – especially of the interior of the
fitting – is avoided. Follow the limit values for ambient
temperature. When transporting the device to a remote
mounting location, we recommend that you reuse the
factory-issued packaging and the transport protection.
17 Maintenance
The device requires no maintenance if used according to its
intended purpose. However, if cleaning is necessary to
remove dirt from the measuring ring or the measuring body,
take note of the following aspects:
- Please take note that, with devices with built-in
electrical equipment, removing the indicator cover
restricts the EMC protection.
- Before removing a device, make sure that the pipeline
is free from the product, is pressureless and has cooled
down.
- Fittings with the insides coated may be carefully
cleaned after removal with a brush and the appropriate
cleansing agent. Carefully clean the measuring body
from possible coating. Attention: do not use the
measuring ring/cone and the measuring body with hard
objects (see Removing/installing the measuring body).
- The switching points of the limit transducers are
adjustable. To do this, remove the indicator cover,
unfasten the contact point indicator located on the scale
and readjust it. After the adjustment, reattach the bolts
Page 18 of 29

Heinrichs Messtechnik BGF Installation and Operating Instructions
of the contact point indicator. Reinstall and tighten the
indicator cover.
- The calibration of the KINAX signal output is firmly set
and not adjustable. Do not adjust the potentiometer of
the transmitter.
- The parameterization of the ES is possible and is done
via HART®. Please refer to the separate Operating
Instructions for the ES.
18 Installing and removing the
resetting spring and the
measuring body
The interior structure of the devices differ according to
nominal size.
DN 15 and DN 25: To remove the resetting spring, secure
the measuring body from turning by using a suitable tool
from above. Unscrew the lock nuts from below and remove
the spring. The measuring body can be pulled out upwards
after removing the bottom guide.
DN 40/DN 50 and DN 80: To remove the return spring,
press the cross-bar downwards from both lateral locking
brackets. Since the locking brackets are compressed
together beneath the bar, some force must be applied. After
the bar is removed, the spring can now be taken out from
above. To disassemble the measuring body, secure it from
turning by using a suitable tool, remove the nuts and guide
brackets from below and then pull the measuring body
upwards.
Proceed in reverse order when reinstalling thesed parts.
19 Trouble shooting
- Indicator window clouds over: Water in the indicator
unit.
- Indicator cover is not tight enough: Adjust the cover
seal, tighten the cover.
- Window is opaque: Corrosive atmosphere, ventilate.
- Window ices over due to cold and damp
atmosphere: The device can be equipped at the
factory with an air/nitrogen flush.
- Window ices over due to very cold medium and
damp atmosphere: The device can be equipped at
the factory with a pulled-forward indicator unit.
- Device shows incorrect values: Compare process
data, density, viscosity, temperature and pressure with
the values on the scale. If they deviate, convert the
scale values using the VDE/VDI 3513 standard; for the
signal output 2 option, carry out reparameterization.
- Pointer does not react in spite of varying flow: The
pointer may have gotten stuck; remove the cover and
move the pointer; if the pointer can be moved easily,
the measuring body cannot move. If the pointer is
unable to move further, send the device to the head
office for servicing.
- Measuring body is stuck at one place because of
dirt: Disassemble the device, if necessary disassemble
and clean the measuring body, install a magnetic filter if
there are magnetic contaminants.
- Measuring body is stuck at one place because the
resetting spring is deformed or broken: Send the
device to our head office for servicing and, if necessary,
replace the spring and the measuring body.
- Scale pointer pulsates: Increase the supply pressure
when measuring gas. Alternatively, mount an aperture
plate behind the device and check whether the valve is
mounted behind the device. Select the device with the
smallest possible pressure loss. Adjust to the desired
flow rate, run at 100%. Select a short distance between
the flowmeter and the downstream throttle point (valve).
When dealing with liquids, prevent pulsation of the
product by using a volume receptacle.
- Electrical equipment are not functioning: Check the
auxiliary power. Are suitable power supply equipment
connected, have the terminals been selected correctly,
has the parameterization carried out correctly?
20 Returning devices for repair and
service
